Function Documentation

DDS_SequenceNumber_compare()

DDSCDllExport int DDS_SequenceNumber_compare	(	const struct DDS_SequenceNumber_t *	sn1,
		const struct DDS_SequenceNumber_t *	sn2 )

Compares two sequence numbers.

Parameters

sn1	<<in>> Sequence number to compare. Cannot be NULL.
sn2	<<in>> Sequence number to compare. Cannot be NULL.

Returns

If the two sequence numbers are equal, the function returns 0. If sn1 is greater than sn2 the function returns a positive number; otherwise, it returns a negative number.
